摘　　要：介绍了以电荷耦合面阵成象器件作为传感器的近红外成象制导系统。在系统中,采用了一些关键技术——时域选通及频域滤波技术来抑制电信号干扰,还采用了波门跟踪及航迹预测技术来增强系统的抗干扰能力;采用近红外带通滤波技术使系统工作于近红外波段,并使合作目标产生的光谱与之匹配,来提高系统输出信号/噪声比。还在制导精度、响应速度等方面采取了特殊措施,从而使系统性能优良、结构简单、价格低廉。The new IR imaging guide system using charge coupled plane array imaging device as sensor is presented. Some key technologies—such as time domain gate and frequency domain filtering—are used to restrict electric signal interference. The window tracking and flight path forecasting are applied to strengthening the antiinterference capability of the system. The near IR bandpass filtering enables the system to operate in near IR band, thus the spectrum of the cooperative object matches with it, and the output signal/noise ratio of the system can be raised. Some special measures have been adopted in the guide accuracy and response speed. The system is very simple and its performances are good.
